First post for me. I recently bought a Sony DVP-NS725P DVD player which only plays region 1. (If anyone has tips on how make it multi-region please let me know) The player is supposed to play DVD-R, DVD-RW, DVD+R, DVD+RW, however when I burn .img files with Disk Utility they won't play. It says "Playback prohibited by area limitations." First time I tried it with a DVD-RW from Japan, so I figured that was the problem, so I went out to get some burnable DVD's from walmart but to my surprise I got the same message. Is it because of Disk Utility? Any suggestions? Thanks!
